Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-62429 in the wild and no public exploit code.\n\nAffected product: Xen. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-62429/ (Markdown: https://insights.sbomify.com/CVE-2026-62429/index.md)","id":"CVE-2026-62429","markdown":"https://insights.sbomify.com/CVE-2026-62429/index.md","name":"CVE-2026-62429","record":{"aliases":["ALPINE-CVE-2026-62429","DEBIAN-CVE-2026-62429","GHSA-8fgv-987v-pg9v","UBUNTU-CVE-2026-62429"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["denial_of_service","other"],"network_reachable":"yes","non_default_config":false,"product_category":"Xen hypervisor","requires_auth":"low_privilege","summary":"A race condition in Xen's vNUMA cleanup allows device models to access destroyed domain data, potentially causing crashes or undefined behavior.","user_interaction":"not_required","vuln_class":"race_condition"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"XEN","cpe":[],"cvss":{"score":6.5,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-362","name":"Concurrent Execution using Shared Resource with Improper Synchronization"}],"description":"Accessing the vNUMA configuration data of a guest is still possible when\ndomain destruction has already started.
